Evaluation of FKBP and DHFR based destabilizing domains in Saccharomyces cerevisiae.

ABSTRACT: Two orthogonal destabilizing domains have been developed based on mutants of human FKBP12 as well as bacterial DHFR and these engineered domains have been used to control protein concentration in a variety of contexts in vitro and in vivo. FKBP12 based destabilizing domains cannot be rescued in the yeast Saccharomyces cerevisiae; ecDHFR based destabilizing domains are not degraded as efficiently in S. cerevisiae as in mammalian cells or Plasmodium, but provide a starting point for the development of domains with increased signal-to-noise in S. cerevisiae.

Recent progress with FKBP-derived destabilizing domains.

Project description:The FKBP-derived destabilizing domains are increasingly being used to confer small molecule-dependent stability to many different proteins. The L106P domain confers instability to yellow fluorescent protein when it is fused to the N-terminus, the C-terminus, or spliced into the middle of yellow fluorescent protein, however multiple copies of L106P do not confer greater instability. These engineered destabilizing domains are not dominant to endogenous degrons that regulate protein stability.

Engineering FKBP-Based Destabilizing Domains to Build Sophisticated Protein Regulation Systems.

Project description:Targeting protein stability with small molecules has emerged as an effective tool to control protein abundance in a fast, scalable and reversible manner. The technique involves tagging a protein of interest (POI) with a destabilizing domain (DD) specifically controlled by a small molecule. The successful construction of such fusion proteins may, however, be limited by functional interference of the DD epitope with electrostatic interactions required for full biological function of proteins. Another drawback of this approach is the remaining endogenous protein. Here, we combined the Cre-LoxP system with an advanced DD and generated a protein regulation system in which the loss of an endogenous protein, in our case the tumor suppressor PTEN, can be coupled directly with a conditionally fine-tunable DD-PTEN. This new system will consolidate and extend the use of DD-technology to control protein function precisely in living cells and animal models.

Non-antibiotic Small-Molecule Regulation of DHFR-Based Destabilizing Domains In Vivo.

Project description:The E. coli dihydrofolate reductase (DHFR) destabilizing domain (DD), which shows promise as a biologic tool and potential gene therapy approach, can be utilized to achieve spatial and temporal control of protein abundance in vivo simply by administration of its stabilizing ligand, the routinely prescribed antibiotic trimethoprim (TMP). However, chronic TMP use drives development of antibiotic resistance (increasing likelihood of subsequent infections) and disrupts the gut microbiota (linked to autoimmune and neurodegenerative diseases), tempering translational excitement of this approach in model systems and for treating human diseases. Herein, we identified a TMP-based, non-antibiotic small molecule, termed 14a (MCC8529), and tested its ability to control multiple DHFR-based reporters and signaling proteins. We found that 14a is non-toxic and can effectively stabilize DHFR DDs expressed in mammalian cells. Furthermore, 14a crosses the blood-retinal barrier and stabilizes DHFR DDs expressed in the mouse eye with kinetics comparable to that of TMP (≤6 h). Surprisingly, 14a stabilized a DHFR DD in the liver significantly better than TMP did, while having no effect on the mouse gut microbiota. Our results suggest that alternative small-molecule DHFR DD stabilizers (such as 14a) may be ideal substitutes for TMP in instances when conditional, non-antibiotic control of protein abundance is desired in the eye and beyond.

Synthesis and analysis of stabilizing ligands for FKBP-derived destabilizing domains.

Project description:We recently identified mutants of the human FKBP12 protein that are unstable and rapidly degraded when expressed in mammalian cells. We call these FKBP mutants destabilizing domains (DDs), because their instability is conferred to any protein fused to the DDs. A cell-permeable ligand binds tightly to the DDs and prevents their degradation, thus providing small molecule control over intracellular protein levels. We now report the synthesis and functional characterization of a stabilizing ligand called Shield-2. The synthesis of Shield-2 is efficient, and this ligand binds to the FKBP(F36V) protein with a dissociation constant of 29 nM.

Genome destabilizing mutator alleles drive specific mutational trajectories in Saccharomyces cerevisiae.

Project description:In addition to environmental factors and intrinsic variations in base substitution rates, specific genome-destabilizing mutations can shape the mutational trajectory of genomes. How specific alleles influence the nature and position of accumulated mutations in a genomic context is largely unknown. Understanding the impact of genome-destabilizing alleles is particularly relevant to cancer genomes where biased mutational signatures are identifiable. We first created a more complete picture of cellular pathways that impact mutation rate using a primary screen to identify essential Saccharomyces cerevisiae gene mutations that cause mutator phenotypes. Drawing primarily on new alleles identified in this resource, we measure the impact of diverse mutator alleles on mutation patterns directly by whole-genome sequencing of 68 mutation-accumulation strains derived from wild-type and 11 parental mutator genotypes. The accumulated mutations differ across mutator strains, displaying base-substitution biases, allele-specific mutation hotspots, and break-associated mutation clustering. For example, in mutants of POLα and the Cdc13-Stn1-Ten1 complex, we find a distinct subtelomeric bias for mutations that we show is independent of the target sequence. Together our data suggest that specific genome-instability mutations are sufficient to drive discrete mutational signatures, some of which share properties with mutation patterns seen in tumors. Thus, in a population of cells, genome-instability mutations could influence clonal evolution by establishing discrete mutational trajectories for genomes.

Utility of the DHFR-based destabilizing domain across mouse models of retinal degeneration and aging.

Project description:The Escherichia coli dihydrofolate reductase (DHFR) destabilizing domain (DD) serves as a promising approach to conditionally regulate protein abundance in a variety of tissues. To test whether this approach could be effectively applied to a wide variety of aged and disease-related ocular mouse models, we evaluated the DHFR DD system in the eyes of aged mice (up to 24 months), a light-induced retinal degeneration (LIRD) model, and two genetic models of retinal degeneration (rd2 and Abca4 -/- mice). The DHFR DD was effectively degraded in all model systems, including rd2 mice, which showed significant defects in chymotrypsin proteasomal activity. Moreover, trimethoprim (TMP) administration stabilized the DHFR DD in all mouse models. Thus, the DHFR DD-based approach allows for control of protein abundance in a variety of mouse models, laying the foundation to use this strategy for the conditional control of gene therapies to potentially treat multiple eye diseases.

Identification of destabilizing and stabilizing mutations of Ste2p, a G protein-coupled receptor in Saccharomyces cerevisiae.

Project description:The isolation of mutations affecting the stabilities of transmembrane proteins is useful for enhancing the suitability of proteins for structural characterization and identification of determinants of membrane protein stability. We have pursued a strategy for the identification of stabilized variants of the yeast ?-factor receptor Ste2p. Because it was not possible to screen directly for mutations providing thermal stabilization, we first isolated a battery of destabilized temperature-sensitive variants, based on loss of signaling function and decreased levels of binding of the fluorescent ligand, and then screened for intragenic second-site suppressors of these phenotypes. The initial screens recovered singly and multiply substituted mutations conferring temperature sensitivity throughout the predicted transmembrane helices of the receptor. All of the singly substituted variants exhibit decreases in cell-surface expression. We then screened randomly mutagenized libraries of clones expressing temperature-sensitive variants for second-site suppressors that restore elevated levels of binding sites for fluorescent ligand. To determine whether any of these were global suppressors, and thus likely stabilizing mutations, they were combined with different temperature-sensitive mutations. Eight of the suppressors exhibited the ability to reverse the defect in ligand binding of multiple temperature-sensitive mutations. Combining certain suppressors into a single allele resulted in levels of suppression greater than that seen with either suppressor alone. Solubilized receptors containing suppressor mutations in the absence of temperature-sensitive mutations exhibit a reduced tendency to aggregate during immobilization on an affinity matrix. Several of the suppressors also exhibit allele-specific behavior indicative of specific intramolecular interactions in the receptor.

Comparative analysis of Saccharomyces cerevisiae WW domains and their interacting proteins.

Project description:The WW domain is found in a large number of eukaryotic proteins implicated in a variety of cellular processes. WW domains bind proline-rich protein and peptide ligands, but the protein interaction partners of many WW domain-containing proteins in Saccharomyces cerevisiae are largely unknown.We used protein microarray technology to generate a protein interaction map for 12 of the 13 WW domains present in proteins of the yeast S. cerevisiae. We observed 587 interactions between these 12 domains and 207 proteins, most of which have not previously been described. We analyzed the representation of functional annotations within the network, identifying enrichments for proteins with peroxisomal localization, as well as for proteins involved in protein turnover and cofactor biosynthesis. We compared orthologs of the interacting proteins to identify conserved motifs known to mediate WW domain interactions, and found substantial evidence for the structural conservation of such binding motifs throughout the yeast lineages. The comparative approach also revealed that several of the WW domain-containing proteins themselves have evolutionarily conserved WW domain binding sites, suggesting a functional role for inter- or intramolecular association between proteins that harbor WW domains. On the basis of these results, we propose a model for the tuning of interactions between WW domains and their protein interaction partners.Protein microarrays provide an appealing alternative to existing techniques for the construction of protein interaction networks. Here we built a network composed of WW domain-protein interactions that illuminates novel features of WW domain-containing proteins and their protein interaction partners.

High-resolution NMR structures of the domains of Saccharomyces cerevisiae Tho1.

Project description:THO is a multi-protein complex involved in the formation of messenger ribonuclear particles (mRNPs) by coupling transcription with mRNA processing and export. THO is thought to be formed from five subunits, Tho2p, Hpr1p, Tex1p, Mft1p and Thp2p, and recent work has determined a low-resolution structure of the complex [Poulsen et al. (2014), PLoS One, 9, e103470]. A number of additional proteins are thought to be involved in the formation of mRNP in yeast, including Tho1, which has been shown to bind RNA in vitro and is recruited to actively transcribed chromatin in vivo in a THO-complex and RNA-dependent manner. Tho1 is known to contain a SAP domain at the N-terminus, but the ability to suppress the expression defects of the hpr1Δ mutant of THO was shown to reside in the RNA-binding C-terminal region. In this study, high-resolution structures of both the N-terminal DNA-binding SAP domain and C-terminal RNA-binding domain have been determined.

Compositional and structural analysis of selected chromosomal domains from Saccharomyces cerevisiae.

Project description:Chromatin is the template for replication and transcription in the eukaryotic nucleus, which needs to be defined in composition and structure before these processes can be fully understood. We report an isolation protocol for the targeted purification of specific genomic regions in their native chromatin context from Saccharomyces cerevisiae. Subdomains of the multicopy ribosomal DNA locus containing transcription units of RNA polymerases I, II or III or an autonomous replication sequence were independently purified in sufficient amounts and purity to analyze protein composition and histone modifications by mass spectrometry. We present and discuss the proteomic data sets obtained for chromatin in different functional states. The native chromatin was further amenable to electron microscopy analysis yielding information about nucleosome occupancy and positioning at the single-molecule level. We also provide evidence that chromatin from virtually every single copy genomic locus of interest can be purified and analyzed by this technique.
